Dark spots on baby forehead?

My baby is 4 months old and he has started developing some sort of dark spots on his forehead. It is his whole forehead that has darker spots on it. My baby is mixed, black and white. Does anyone know what could be causing this? Will it stay like this? We have asked his doctor and she says it may be due to craddle cap, but i have done some researching and see this as no association with craddle cap. I can not find any info with this occuring in other babies. I have a picture, but not sure how to attach??
